How-To Guide

1. K-means clustering is a popular unsupervised machine learning algorithm that groups data points into K clusters based on their similarities. In this guide, we will walk you through how to implement K-means clustering using the scikit-learn library in Python.
2. Step 1: Install scikit-learn
3. If you haven't already installed scikit-learn, you can do so using pip:
4. ```bash
5. pip install scikit-learn
6. ```
7. Step 2: Import the necessary libraries
8. First, you need to import the required libraries:
9. ```python
10. import numpy as np
11. from sklearn.cluster import KMeans
12. ```
13. Step 3: Prepare your data
14. Next, you need to prepare your data for clustering. Make sure your data is in the form of a numpy array or pandas DataFrame.
15. ```python
16. data = np.array([[1, 2], [5, 8], [5, 8], [8, 8], [1, 0.6], [9, 11]])
17. ```
18. Step 4: Instantiate the KMeans class
19. Now, you can instantiate the KMeans class with the desired number of clusters (K) and fit the model to your data.
20. ```python
21. kmeans = KMeans(n_clusters=2)
22. kmeans.fit(data)
23. ```
24. Step 5: Get the cluster labels
25. You can now get the cluster labels for each data point in your dataset.
26. ```python
27. labels = kmeans
